乳部的病症多与肝、胃、心、脾有关，因为乳头归属于肝经，乳房归属于胃经，而心和脾的气机郁结，常导致乳核、乳岩等病症。乳痈（急性乳腺炎）表现为肿胀且颜色发红，属于阳证，多由热毒引起，多见于妇女，脓液溃破后容易痊愈。乳岩（乳腺癌）表现为结核状肿块且颜色发白，属于阴证，多由痰凝所致，男女皆有，但寡妇和孤独者居多，一旦溃破则难以治疗。而且，患病乳房若有婴儿吮吸乳汁则容易痊愈，若无婴儿吮吸则难康复。至于乳漏等症，日久会转为囊肿并穿破，洞见肺腑，损伤极大无法恢复，难以挽回。而乳岩尤为根部坚硬难以切除，有的经历数年才疼痛，经历十几年才溃破，此时救治已晚，一旦溃破便无法治愈。必须长期服用归脾汤、养荣汤等方剂。切忌使用攻伐坚固或解毒的药物，以免损伤元气，加速死亡。
乳汁是由气血化生而成，其源头在于胃，实际上是水谷精微的精华。由于冲脉隶属于胃，所以气上升化为乳汁，下降则为月经。新产妇产后三天出现寒热症状，称为“蒸乳”。宜用逍遥散去白术。年轻妇女初次生产，乳房胀痛且乳汁不通畅，宜用清热利湿的方法。可用连翘金贝煎。若生产次数多而乳汁少，是由于气血不足，宜用滋补法。可用异功散加当归、白芍、枸杞子、熟地黄、瓜蒌仁，仍以羹汤引服。产后乳汁自出，属于胃气虚，宜用固补法，可用七福饮加黄芪、五味子以收敛固摄。乳汁过多且胀痛外溢者，用温热的布巾熨敷以消散之。小儿吮吸乳汁时，若鼻吹入风邪，导致乳房壅结肿痛，称为“外吹”，若不急治，多成乳痈。
内服栝蒌散，外用天南星末敷贴。严重者用连翘金贝煎。孕妇因胎热，出现寒热及乳房肿胀，称为“内吹”，用橘叶散治疗。新生儿未能吮吸乳汁，余乳停蓄导致乳房胀大，伴有发热口渴、肿硬结痛，称为“妒乳”（积乳）。宜挤去宿乳，或用嘴吮通。可用贝母、栝蒌、甘草节、木通煎服。倘若婴儿夭折，产妇出现蒸乳寒热胀痛，宜采用断乳法，用炒麦芽一两煎服以消散乳汁。有气血颇壮盛，但乳汁不即下者，可用通草猪蹄汤、通草散，或秘传涌泉散来通乳。若因痰气阻滞经络导致乳汁不下，多见于肥胖之人，可用神效栝蒌散疏降痰气。或用丝瓜络连子烧存性，酒送服三钱，盖被取汗，即可通乳。若因气血虚亏导致乳汁不下，可用玉露散，或八珍汤加黄芪、麦冬调补。因肺胃虚寒导致乳汁不下，可用千金钟乳汤温养。
妇女胆、胃二经受热毒壅遏气血，导致乳房肿痛，称为乳痈。初起时有寒热肿痛，肌肉颜色赤红，宜凉血疏邪。可用四物汤加柴胡、山栀、丹皮、贝母、栝蒌、甘草。乳房结核，肿痛且色赤，宜疏肝清胃。内服牛蒡子汤，外用活鲤鱼，连同头骨捣烂，加入香腊槽一团研匀敷上，即可消散。若气血凝滞，结核不散，用连翘饮子。肝失条达舒畅，导致乳痈结核，伴有寒热肿溃，用清肝解郁汤。心脾郁伤，导致乳痈发热，结核腐溃，用归脾汤，黄芪、白术、甘草生用。乳部肿痛，用大贝母、白芷、乳香、没药、当归身，每服四钱，白酒送下。乳部溃烂，用两头尖雄鼠粪、土楝子（经霜者佳）、露蜂房各三钱，均烧存性，研末，分三次酒送服，隔两日服一次。痛止脓敛，若脓成不溃，或脓水清稀，用托里消毒散。溃破久不愈合，用桑根木芝，或菌类，烧灰，配合冰片末掺敷，即可痊愈。
乳内结成一粒如豆大小的小核，不红不痛，伴有内热体倦，月经不调，称为乳岩。需及早调治，若年久逐渐变大，肿硬如石，时常发生抽痛，数年溃烂腐坏，如岩石深洞，血水淋漓者，属不治之症。溃后大如倒扣的碗，不痛而极痒者，是内生蛆虫所致。此症因忧思郁结，亏损肝脾气血而成。初起小核，可用生蟹壳爪数十枚，在砂锅内焙干，研末酒送服，再用当归、陈皮、枳实、贝母、连翘、生姜、白芷、甘草节煎服数十剂，不间断服用，可消除。蟹爪灰与煎剂交替服用，曾经验证有效。若未消除，内服益气养荣汤，外用木香饼熨敷。阴虚午后发热，用加味逍遥散去焦白术，加熟地黄。寒热抽痛，用归脾汤。元气削弱，大剂量人参煎服可消除。若用攻伐坚固解毒之法，必致溃败无法挽救。凡溃后，最忌使用乳没等药物。
产后两乳房伸长，细如鸡肠，垂至小腹以下，疼痛难以忍受，称为乳悬，这是怪症，偶尔也有发生。急用川芎、当归各一斤，切片，只取四两，水煎服。令产妇伏在桌上，下方放置火炉，将剩余的川芎、当归片放入炉中慢慢燃烧，让产妇口鼻及乳房吸入烟雾使其上行，若药尽仍未收回，按前述方法煎服熏吸，便可缩回。否则用蓖麻子三粒，研碎涂于头顶心。片刻后即擦去，即可收回。
Breast diseases are primarily associated with the Liver, Stomach, Heart, and Spleen. The nipple belongs to the Liver Meridian (Liver Channel), while the breast tissue belongs to the Stomach Meridian (Stomach Channel). Depression and stagnation of the Heart and Spleen often manifest as symptoms such as *Ru He* (Breast Nodule) and *Ru Yan* (Breast Rock/Cancer). *Ru Yong* (Acute Mastitis) presents with swelling and redness, belonging to Yang patterns, typically caused by Heat-Toxin. It is common in women; once pus discharges, it heals easily. *Ru Yan* (Breast Cancer) presents as a white-colored nodule, belonging to Yin patterns, typically caused by Phlegm coagulation. It occurs in both men and women but is more frequent among widows and isolated individuals. Once ulcerated, it is difficult to treat. Furthermore, if an infant suckles the affected breast, healing is easier; without suckling, recovery is difficult. Conditions such as *Ru Li* (Breast Fistula) may, over time, transform into cysts that perforate, exposing internal organs, causing extreme damage that is irreversible. *Ru Yan* (Breast Cancer) is particularly characterized by a hard root that is difficult to excise. Some patients experience pain only after several years, or ulceration after ten-plus years. By the time pain begins, treatment is delayed; once ulcerated, it is incurable. Long-term administration of *Guipi Tang* (Restore the Spleen Decoction) and *Yangrong Tang* (Nourish the Nutrient Decoction) is required. One must strictly avoid harsh attacking or detoxifying herbs that damage Yuan Qi (Original Qi) and accelerate death.
Milk is transformed from Qi and Blood, originating from the Stomach, and represents the essence of food and water. Since the Chong Mai (Penetrating Vessel) is subordinate to the Stomach, ascending Qi transforms into milk, while descending Qi becomes menstruation. Three days postpartum, the onset of chills and fever is termed "Zheng Ru" (Steaming Milk). Treatment should use *Xiaoyao San* (Free and Easy Wanderer Powder) with Bai Zhu (Atractylodis Rhizoma) removed. For young women giving birth for the first time, if breasts are distended and milk flow is obstructed, clear heat and promote drainage using *Lianqiao Jinbei Jian* (Forsythia and Fritillaria Decoction). If multiparity results in low milk supply due to Qi and Blood deficiency, tonify using *Yigong San* (Extraordinary Aid Powder) modified with Dang Gui (Angelicae Sinensis Radix), Bai Shao (Paeoniae Radix Alba), Gou Qi Zi (Lycii Fructus), Shu Di Huang (Rehmanniae Radix Praeparata), and Gua Lou Ren (Trichosanthis Semen). Administer with soup broth. Spontaneous lactation postpartum indicates Stomach Qi deficiency; secure and tonify using *Qifu Yin* (Seven Blessings Decoction) modified with Huang Qi (Astragali Radix) and Wu Wei Zi (Schisandrae Fructus) to astringe. Excessive milk with distension and pain can be dispersed by applying warm cloth compresses. Infant suckling combined with wind exposure causing breast congestion, nodularity, and pain is called "Wai Chui" (External Blowing); if not treated urgently, it often develops into *Ru Yong* (Acute Mastitis).
Internally administer *Gualou San* (Trichosanthes Powder), externally apply Tian Nan Xing (Arisaematis Rhizoma) powder. Severe cases use *Lianqiao Jinbei Jian*. In pregnant women, fetal heat causing chills, fever, and breast swelling is called "Nei Chui" (Internal Blowing), treated with *Juye San* (Citrus Aurantium Leaf Powder). If a newborn cannot suckle, retained milk causes breast distension, fever, thirst, hardness, and pain, termed "Du Ru" (Jealous Milk). Squeeze out retained milk or encourage drainage via suckling. Use Bei Mu (Fritillariae Bulbus), Gualou (Trichosanthis Fructus), Gan Cao Jie (Glycyrrhizae Radix et Rhizoma with knot), and Mu Tong (Akebiae Caulis) decoction. If the infant dies, and the mother experiences steaming milk with chills, fever, distension, and pain, use weaning methods: decoct 1 liang of Chao Mai Ya (Fried Hordei Fructus Germinatum) to dissipate milk. For those with strong Qi and Blood but delayed lactation, use *Tongcao Zhuti Tang* (Akebia and Pig Trotter Decoction), *Tongcao San*, or the secret formula *Yongquan San*. If Phlegm-Qi blocks the meridians preventing lactation (common in obese individuals), use *Shenxiao Gualou San* to diffuse and descend. Alternatively, burn Si Gua Luo Lian Zi (Luffae Fructus Retinervus cum Semine) until charred on the outside, take 3 qian with wine, cover up to induce sweating, which will unblock flow. For Qi and Blood deficiency causing no lactation, use *Yulu San* or *Bazhen Tang* (Eight Treasures Decoction) modified with Huang Qi and Mai Dong (Ophiopogonis Radix) to tonify. For Lung-Stomach Deficiency-Cold causing no lactation, use *Qianjin Zhongru Tang* (Thousand Gold Calcite Decoction) to warm and nourish.
Heat-Toxin in the Gallbladder and Stomach meridians obstructing Qi and Blood causes breast swelling and pain, known as *Ru Yong* (Acute Mastitis). Initial stage with chills, fever, swelling, pain, and red skin requires cooling blood and dispersing pathogens. Use *Siwu Tang* (Four Substances Decoction) modified with Chai Hu (Bupleuri Radix), Shan Zhi (Gardeniae Fructus), Dan Pi (Moutan Cortex), Bei Mu, Gualou, and Gan Cao. Breast nodules with swelling, pain, and redness require soothing the Liver and clearing the Stomach. Internally use *Niubangzi Tang* (Arctii Fructus Decoction); externally, mash live carp including head bones, mix with one ball of Xiang La Cao (Incense Wax Residue), grind evenly, and apply to dissipate. For Qi-Blood stasis with persistent nodules, use *Lianqiao Yinzi* (Forsythia Infusion). For Liver failure to maintain smooth flow causing *Ru Yong* nodules with chills, fever, swelling, and ulceration, use *Qinggan Jieyu Tang* (Clear Liver and Resolve Depression Decoction). For Heart-Spleen depression causing *Ru Yong* fever, nodules, and ulceration, use *Guipi Tang* with raw Huang Qi, Bai Zhu, and Gan Cao. For breast swelling and pain, use Da Bei Mu (Fritillariae Thunbergii Bulbus), Bai Zhi (Angelicae Dahuricae Radix), Ru Xiang (Olibanum), Mo Yao (Myrrha), and Dang Gui Shen (Dang Gui Root Tip), 4 qian per dose taken with white wine. For breast ulceration, use Liang Tou Jian (Phragmitis Rhizoma) and male rat feces, Tu Lian Zi (Toosendan Fructus - best after frost), and Lu Feng Fang (Vespa Nidus), each 3 qian, burned to preserve nature, ground to powder, divided into three doses taken with wine, every two days. When pain stops and pus consolidates, if pus forms but does not discharge, or pus is thin and clear, use *Tuoli Xiaodu San* (Support Interior and Eliminate Toxin Powder). For chronic non-healing ulcers, use Sang Gen Mu Zhi (Mulberry Root Bark Polypore) or fungi, burned to ash, mixed with Bing Pian (Borneolum Syntheticum) powder and applied.
A small bean-sized nodule in the breast, non-red, non-painful, accompanied by internal heat, fatigue, and irregular menstruation, is called *Ru Yan* (Breast Rock/Cancer). Treat early. If it grows large over years, becomes stone-hard, with intermittent pulling pain, and eventually ulcerates like a deep rock cavity with bloody discharge, it is incurable. Post-ulceration, if it resembles an inverted bowl, painless but extremely itchy, it indicates maggot infestation internally. This condition arises from worry, thought, and depression damaging Liver and Spleen Qi and Blood. For initial small nodules, roast dozens of raw crab claw shells in a clay pot, grind to powder, take with wine. Then decoct Dang Gui, Chen Pi (Citri Reticulatae Pericarpium), Zhi Shi (Aurantii Fructus Immaturus), Bei Mu, Qiao (Lianqiao), Jiang (Zingiberis Rhizoma), Bai Zhi, and Gan Cao Jie, taking dozens of doses continuously without interruption to eliminate. Alternate crab claw ash with the decoction; this has been verified effective. If not eliminated, internally take *Yiqi Yangrong Tang* (Tonify Qi and Nourish Nutrient Decoction), externally apply *Muxiang Bing* (Costus Cake) compress. For Yin deficiency with afternoon fever, use *Jiawei Xiaoyao San* (Modified Free and Easy Wanderer Powder) removing burnt Bai Zhu, adding Shu Di Huang. For chills, fever, and pulling pain, use *Guipi Tang*. For weakened Yuan Qi, large doses of Ren Shen (Ginseng Radix et Rhizoma) decoction can eliminate it. Using harsh attacking/detoxifying methods will inevitably lead to fatal ulceration. After ulceration, strictly avoid herbs like Ru Xiang and Mo Yao.
Postpartum elongation of both breasts, thin as chicken intestines, hanging below the lower abdomen with unbearable pain, is called *Ru Xuan* (Hanging Breast), a rare anomaly. Urgently use 1 jin each of Xiong (Chuanxiong Rhizoma) and Dang Gui, sliced. Take only 4 liang, decoct in water, and drink. Have the puerpera lie prone on a table with a fire stove underneath. Place remaining Xiong and Dang Gui slices on the stove to smolder slowly. Inhale the smoke through mouth, nose, and breasts to draw them upward. If medicine finishes and breasts do not retract, repeat decoction and fumigation. Otherwise, grind 3 castor beans (Bi Ma Zi), apply to the top of the head (Baihui area). Remove after a short while, and they will retract.
